Hafnium is a silver-gray metal with metallic luster; Its transition temperature is higher than zirconium. The hafnium metal has allergenic variant at high temperature. The metal hafnium has a high neutron absorption cross-section and can be used as a reactor control material. Hafnium chemical properties and zirconium very similar, with good corrosion resistance, not easy to be eroded by general acid and alkali aqueous solution. Pure hafnium with plasticity, easy processing, high temperature resistance and corrosion resistance, is an important material for atomic energy industry. Hafnium is an ideal neutron absorber with large thermal neutron capture cross-section and can be used as control rod and protection device in atomic reactor. Hafnium powder can be used as propellers for rockets. Cathodes for X-ray tubes can be manufactured in the electrical industry. Hafnium alloy can be used as rocket nozzle and glider re-entry aircraft front protection layer, HF-TA alloy can be manufactured tool steel and resistance materials. The screw is a tool for fastening the machine parts step by step by using the physics and mathematics principles of the circular rotation of the inclined plane and friction. Screw is a general term for fastener. Screws are indispensable industrial necessities in daily life: such as cameras, glasses, clocks, electronics, and so on the use of tiny screws; General screws for TV sets, electrical products, Musical Instruments, furniture, etc. As for engineering, construction, bridge use large screws, nuts; Transportation equipment, aircraft, tram, car and so on are both large and small screws. The screw plays an important role in industry. As long as industry exists on earth, the function of the screw will always be important. Screw is a common invention in people's production and life for thousands of years. According to the application field, it is the first great invention of mankind.
